WILLIAM H. STERNS, OF HUMBOLD'I, NEBRASKA.

IMPROVEMENT lN CHURNS.

Specification forming part of Letters Patent No. 218,790, dated August19, 1879 application filed March 12, 1879.

To all whom it may concern Be it known that I, WILLIAM H. STERNs, otHumboldt, in the county of Richardson and State of Nebraska, haveinvented a new and Improved Ghurn, of which the following-is aspecification.

The object of this invention is to provide a i simply-constructed andeasily-operated churn,

wherein the agitation of the cream is produced by the rapid movement ofthe apparatus in a horizontal plane, whereby the cream is thrownviolently from side to side ofthe receptacle, a circular or rotarymovement being prevented by cream-breakers in the sides of thereceptacle.

The invention will be first described in connection with theaccompanying drawings, and then particularly ascertained in the claims.

In the drawings, Figure l is a vertical section of my improvement, andFig. 2 is a top plan of the same.

Similar letters of reference indicate correspending parts.

Referring to the drawings, A represents the base ofthe churn, composedof a T-frame, from'the shank whereof standards B B rise at right anglesto the length of the frame, but with the tops inclined toward eachother, and at the top is fixed a pivot, a, carrying fa groovedband-wheel, C, operated by a crank, b.

Near the level of the base, on the outside of each of the standards, ispivoted a grooved pulley, o, the axis of each being inclined toward theT-head of the base.

D is the movable frame, in the form of a T, of the same length as thebase, and having braces d d extending from the head to the shank. On theunder side of this frame, at each end, are fixed blocks e, with socketsf, and in these sockets are confined spherical rollers g, between theunder side of the frame and the upper side of the base, while cranks hare pivoted at opposite ends to the frame D and base A, near each end ofthe two Ts, and thus connect the frame and base together, the former,however, being allowed a horizontal rotary motion equal to double thelength of the cranks that connect it with the base.

On top of the frame D is placed, crosswise of the shank and parallel tothe' head, a bar, i.

E is the cream receptacle, set upon the frame D, It has a flangedbottom, j, which sets over and receives the bar t', to which it isfastened, and is thus held to the frame.

Cleats k k have their ends placed against the outside of tlange j, onopposite sides, and

are secured to the frame by-screws or bolts, asv lmay be preferred.These, together with the cross-bar i, attach the receptacle to theframe.

On the upper side of frame A is pivoted a grooved pulley, l, to the axlem of which is eccentricallysecured a ring, Z, which is pivoted to theunder side of the frame D, by means of which the said frame is caused torotate.

A band, F, runs over wheel G, down to pulleys c, thence horizontally topulley l.

By turning band-wheel C motion is communicated to pulley l, and throughits connection therewith the frame D is moved from the center of thepulley l on its bearings, describing a circle, and the receptacle E iscarried `with it.

A verytrapid motion can thus be communicated to the receptacle, and thecream being placed therein is violently agitated, it being 'preventedfrom rotating with the churn by the breakers a on the inside of thereceptacle. It is thus thrown violently from side to side, and by theconcussion the globules are broken, and hence the action is much moreuniform and effective than that produced by the usual reciprocating androtary dashers.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. As an improvement in churns, the base A, incombination with movable frame D, carrying the cream-receptacle E,connected with the frame by cranks h and resting upon spherical rollersg, whereby the said frame and cream-receptacle are enabled to move onthe said base with a rotary motion to agitate the cream in thereceptacle, substantially as described.

2. In combination with movable frame D,

carrying cream-receptacle E, and connected frame and cream-receptacle,substantially as with the base in the manner described, the described.band-wheel pulleys c 0,'pul1ey l, und ring l l', cceentricully securedto the axle n1 of the pulley l, and pivoted to the under side of theWitnesses: frame 1), with the frame I), whereby motion is communicatedthrough belt F to the Suid VVILLIAM H. STERNS.
